As my eyes adjusted, I realized that this seemingly solid carpet of green was actually a large, dense grouping of water hyacinth, throbbing with electric blue and crimson dragonflies, spindly mottled spiders and monstrous ants.
But they did more than just survive in the grass green water, dense with algae and other substances, known and unknown.
From a molecule's point of view, a gel consists of a dense network of strands interspersed with water.
In other words, cloud seeding is designed to produce and store water from moisture-dense clouds in preparation for a drought but not necessarily to end one.
Along with the benefits of urbanization, including lower environmental impact, come challenges such as how to provide large, dense and growing populations with clean water for a growing middle-class with corresponding expectations.
Besides the larger number of emigrant rocks from its surface, Mars cooled faster than the earth after it formed, and so would have reached conditions favourable to life (a dense atmosphere, allowing for surface water) earlier.
The study estimates that roughly half of that 0.43 inch rise was caused by thermal expansion of the oceans (as water warms, it becomes less dense and expands), some from from runoff from melting glaciers, and the rest from melting of Greenland and Antarctica ice sheets.
FORBES: Man The Lifeboats! Global Warming Has Oceans Rising At Alarming Rate! (Or Maybe not)
And now the Arctic's upper layers are getting less dense, for several reasons: melting Arctic glaciers, rising surface-water temperatures, increased precipitation and an absence of salt concentrations resulting from sea-ice formation.
The ways to accommodate such growth in an already dense and developed city inherently tend to be green: improving public transport, redeveloping brownfields, making infrastructure and water supply more reliable and efficient.
